when a girl in a bikini lies down and her hip bones protrude well past their flat stomach causing their bikini bottom to stretch across and gap is formed for a beautiful view of their vaginal front also referred to as hood.

An incredibly sexy phenomenon wherein bikini bottoms are suspended between the two hip bones, causing a space between the bikini and the lower abdomen. This potential view into the unknown can be further accentuated by a third structural element contributing to the bridge-effect, the mound.

The exploding popularity of this peek into the erogenous landscape can be experienced via a simple web search on "Bikini Bridge".
